My bike never wants to start cold...

Recommended Posts

Hey guys so its starting to annoy me that my 350 never wants to start up when I unload it to start riding. it will turn over forever without starting. a tiny bit of starter fluid in the air box and it starts up immediately. after that its fine. Starts up hot first try.

Its not the valves, i just had those adjusted ( 1 intake valve was barely out of spec after 60 hrs.)

The fuel adjustment knob or choke if you like, doesnt seem to help at all

The fuel adjustment knob or choke if you like, doesnt seem to help at all (should I try turning it to add more fuel?)

So... any ideas ?

I learned to just turn it over a few times and walk away. Let it sit for a few minutes while I get everything else ready. Normally fires right off after that. Mechanic said it has to do with the fuel pump pressurizing the system. It was his recommendation to just bump the starter a few times before getting all my gear on. Works great! You might give it a shot!

Look on YouTube as there are some great videos. All you need is a 9v battery, 2 short wires, a 8mm to remove the injector and some brake cleaner.... The whole job should only take about 10min at most...

Does your bike pop at all coming off the throttle? Installed an akro pipe on my bike and had to add 7% more fuel to idle and also increased the fuel % throughout the whole rpm range with the UST. Bike runs great.

Hows the riding in Ft. Myers. Have a place in Naples and just returned. Saw some trails along 75.....

no, no pop but i think it does need more fuel like you said. I want my bike to be running "great" like you say. how do i figure out how mufh more fuel i need? will it increase my consumption considerably?
